JPH05200008A - Electrode of electrocardiograph for animal - Google Patents

Abstract

PURPOSE:To take surely a sharp cardiogram by planting a plurality of highly conductive metal needle on one surface of a metal disc like a frog so that the tips of the frog-like metal needles can reach the surface of any animal's body having long fur. CONSTITUTION:Metal needles 2 are planed on a metal disc 1 like a frog. The metal disc 1 and metal needles 2 may be molded integrally with a high conductive same metal material. The metal needles 2 are arranged in the concentric or any other form, and the number of the planted needles, interval between the needles, thickness and length of the needle are not particularly limited. However, while the tips of the metal needles 2 are preferably sharpened so long as these do not dangerously stick in the skin to provide a sharp cardiograph with reduced electric resistance, all tips of the metal needles 2 need to be arranged at a same level. A cable 3 connected to the metal needle 2 is mounted on the edge or rear surface of metal disc 1. Hands and legs are bound with a band made of an insulating material and applied to the rear surface of the metal disk 1 and a surface fastener or the like as a means for pressing the tips of the metal needles 2 to the skin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an animal electrode for an electrocardiograph, which allows electrocardiographic force to be derived from the skin of an animal in which hair is densely packed without being disturbed by the hair.

[0002]

2. Description of the Related Art Conventionally, when an electrocardiogram of an animal is taken, induction electrodes are attached to a total of three points near the elbows of the left and right forelimbs and the knee of the left hindlimb. In the past, I used to shave my body and attach a disk-shaped electrode for humans to my skin.However, it is a time-consuming task to shave an unanesthetized animal, and until the shave marks are completely covered with hair. It looked bad and was particularly unpopular with the owners of pet animals such as dogs and cats. Therefore, the actual Kaihei 1-10731
Animal-only clip electrodes and needle electrodes as disclosed in Japanese Patent No. 6 have been developed, and have been in use today.

[0003]

The conventional clip electrode is one in which the skin is pinched by the crocodile whose tip is serrated, but the skin covered with hair is slippery,
Electrode detachment tended to occur each time the animal moved.
In addition, since the extra body hair is pinched with the skin, the sensitivity of the electrode tends to be inferior, and even with the help of saline or salt-containing cream, a clear ECG waveform could not be obtained. On the other hand, the needle electrode is used by piercing the skin of a limb or by bending the needle tip into a hook and hooking it. On the other hand, there is an advantage that a clean waveform can be obtained.
A savage way of damaging the skin and causing pain to animals,
I couldn't show it to my owner. The present invention solves the above-mentioned drawbacks of conventional ones, and provides a new animal-specific induction electrode for easily and clearly taking an electrocardiogram without damaging the skin of the animal. The purpose is to do.

[0004]

In order to solve the above-mentioned problems, an animal electrode according to the present invention is provided with a large number of metal needles (2) of good conductivity in a sword-like shape on one side of a metal disk (1). It was planted.

[0005]

The electrode for animals having the above structure is fixed to the extremity with a wearing tool such as a band so that the needle tip touches the skin. A large number of metal needles (2) standing upright in the shape of a sword sew through the gaps between the hair densely formed on the skin to reach the body surface, so that the electromotive force is applied from the needle tip that comes into contact with the skin without being disturbed by the hair. Can be led to an electric meter. In acupuncture, a large number of sewing needles that are bundled in a circle are called "children's needles." Just as the baby's skin never bleeds with this needle, this sword-shaped electrode also has many needles on a disk. There is no danger of damaging the skin of the animal due to its convergence to

FIG. 1 is a side view showing an example of the present invention,
FIG. 2 is a plan view thereof. In the figure, (1) shows a metal disk, (2) shows a metal needle implanted in the shape of a sword, and (3) shows a cable connected to an electrocardiograph. The metal disk (1) and the metal needle (2) may be integrally formed of the same metal material having good conductivity. Alternatively, a circular plate may be made of a material having no electrical conductivity, and the terminals of the electrodes may be embedded in the circular plate so as to be connected to each metal needle. The arrangement of the metal needles (2) is shown in FIG.
It is arbitrary such as concentric circles as shown in. Also, the material, the number and spacing of the needles to be implanted, and the thickness and length are not particularly limited. However, in order to reduce the electric resistance and obtain a clear ECG waveform, make the tips of the metal needles as sharp as possible and align the tips of all the metal needles at the same height as long as there is no risk of piercing the skin. Need to be kept. The cable (3) connected to the metal needle (2) is preferably attached to the edge of the metal disc (1) or the back surface. FIG. 3 is a perspective view showing an example of usage of the animal electrode. As a means for pressing the tip of the metal needle (2) against the skin, a band (4) of an appropriate shape made of an insulating material is applied to the back surface of the metal disc (1) and tied to the limb of the animal with a hook-and-loop fastener or the like. I am allowed to do so.

[0007]

The following epoch-making effects can be obtained by using the animal-specific sword-shaped electrode instead of the conventional clip electrode or needle electrode. (1) No matter how long the hair is, the tip of the sword-shaped electrode needle always reaches the body surface. Therefore, a clear electrocardiogram can be surely obtained. (2) When a sword-shaped needle tip is pressed against the body surface, the skin only dents and the needle does not stick. For this reason, the animals do not dislike electrocardiography because they do not hurt. (3) This electrode can be quickly and easily attached to the elbow or knee of an animal using a band or the like. Therefore, the work is much easier and the work is easier than the conventional method of scraping off the hair and pinching the skin with a clip or piercing a needle. (4) Since this electrode can be hidden behind the band and handled so as not to be seen, unnecessary stress such as fear is not given to the animal. Therefore, it is possible to immediately start taking an electrocardiogram after attaching the electrodes. Therefore, the inspection can be completed in a short time. (5) Unlike conventional needle electrodes that pierce animal limbs,
There is no cruel feeling in electrocardiography using this Kenyama type electrode. Therefore, the owner of the pet animal can easily and safely show the state of the inspection.
